A new method for vertical stratification of zenith tropospheric delay
Advances in Space Research, 2019Abstract Tropospheric delay is an important error source in space geodetic techniques. It varies significantly with height and the height dependent tropospheric error remains one of the major limitations in Global Navigation Satellite System (GNSS) techniques especially in Network Real-Time Kinematic (RTK) with significant topography variations ...

GPS-derived zenith tropospheric delay assimilation into numeric atmosphere model
SPIE Proceedings, 2014© 2014 SPIE. The total zenith tropospheric delay (ZTD) is an important parameter of the atmosphere and directly or indirectly reflects the weather processes and variations. This paper presents a hardware and software complex for continuous measurements and prediction of atmospheric thermodynamics and radiowaves refraction index.

Tropospheric zenith delay monitoring in GPS precise point positioning
SPIE Proceedings, 2009Precise point positioning (PPP) has been demonstrated to be a powerful sensor to monitor tropospheric zenith delay (TZD). In the PPP, some unmodelled biases still remain in the GPS observables and will inevitably degrade the precision of tropospheric zenith delay estimation.

Study on Tropospheric Zenith Delay Solved by GPS Data
2009 First International Conference on Information Science and Engineering, 2009The tropospheric zenith delay of Great Wall station in Antarctic grouped with surrounding IGS stations is solved by GAMIT/GLOBK software using GPS observational data. In the process of solving, IGS final ephemeris and precision forecast ephemeris are used to solve the zenith delay in the software.
